Software that ships, infrastructure that scales.

Tools & platforms

Built on a stack that scales

The platforms and technologies I ship with every day — from AWS serverless to fast no-code and low-code.

What I do

Services

Every service is backed by something real I've already shipped to production.

Custom Full-Stack & SaaS

End-to-end web apps and MVPs — real-time platforms, dashboards, internal tools. From idea to deployed product.

Backed by ScoreFlow (real-time, WebSocket, role-based access).

AWS-Native Architecture

Serverless design, cloud migration and cost optimization with Lambda, DynamoDB, API Gateway, S3 and CloudFront.

60+ Lambdas and 40 tables running in production today.

AI Automation

Personalized email pipelines, content generation, chatbots and lead-nurture flows built directly on Claude and OpenAI.

AI re-engagement system using Claude Haiku + SES on a daily cron.

High-Performance Websites

Conversion-focused landing pages and redesigns tuned for Core Web Vitals in Next.js or WordPress.

~45% checkout conversion and major LCP improvements.

Field, No-Code & Low-Code Apps

Apps that replace paper for construction, inspections and logistics — custom mobile (React Native) or fast no-code/low-code on AppSheet and Base44, with automated reporting.

AppSheet field app across 100+ properties with automatic PDF reports.

Payments & CRM Integrations

Square payments, webhooks, Salesforce Experience Cloud and customer self-service portals connected end to end.

Square payments processed for 200+ customers.

Local SEO & Google Business

Local SEO, Google Business Profile and technical SEO/GEO so customers and AI assistants can find you.

A low-cost recurring entry point that compounds over time.

Selected work

Things I've built

Real products in production — with real users, payments and uptime.

ScoreFlow
Real-time SaaS2026

ScoreFlow

A real-time judging platform for dance competitions — live scoreboards, multi-round scoring and role-based access for organizers, judges and competitors.

The problem

Dance competitions were scored on paper and spreadsheets, causing slow results, errors and no live experience for the audience.

Architecture

Next.js 16 SSR on Lambda with a CloudFront origin split (static to S3, dynamic to Lambda). A WebSocket API backed by a DynamoDB connection registry fans out live scores to scoreboards. FastAPI + AWS CDK backend with Cognito auth and fully isolated prod/QA environments.

Result

Ran a live event with 21 competitors and 9 judges, with 135 scores cast in real time — zero paper, isolated environments and no data bleed.

About

Diego Navas Murcia

Full-Stack & Cloud Engineer

I'm a full-stack and cloud engineer based in Denver/Broomfield, Colorado, with three years building software that runs in production. I work natively with AWS — Lambda, DynamoDB, SES, S3, CloudFront, Cognito and API Gateway — and I build automation directly against the Claude and OpenAI APIs. I work fluently in English and Spanish, which means I can serve Denver's businesses and its Hispanic market without losing anything in translation.
